What’s most distinctive about Tintin is the artwork. Hergé’s trademark ligne claire style, which developed gradually, dispensed with shading and relied on inked lines of uniform weight. To accentuate that line — “the true backbone,” Hergé would insist — colors were restricted to a range of relatively soft tones. Although the characters were cartoon figures, the backgrounds were realistic, even elegant. Hergé did a vast amount of research into cars, ships, airplanes, animals. His pacing and composition owed much to movies.
